2x+y=-4
first put value x=1
= 2x1+y=-4
= 2+y=-4
= y=-4-2
= y=-6
put value x=o
= 2x0+y=-4
= 0+y=-4
= y=-4
A( 0,-4 ) B( 1, -6 )

This is a linear equation of a line
We know that, we need two points minimum to draw a line.
Given line,
2x + y = -4
When, x = -2 , y = 0
When, x = 0 , y = -4
Thus, We have two points,
(-2, -0) and (0, -4)
By joining these points we can get a line for equation 2x+y=-4
